� IGNITION COIL (Checking with Pocket Tester)
● A pocket tester or an ohm meter may be used,
instead of the electro tester. In either case, the igni-
tion coil is to be checked for continuity in both prima-
ry and are secondary windings. Exact ohmic readings
are not necessary, but, if the windings are in sound
condition, their continuity will be noted with approxi-
mate ohmic values.

� SPARK PLUG
Clean the plug with a wire brush and pin. Use the pin to
remove carbon, taking care not to damage the porce-
